That means you need a video card which has HDMI 2.0a, a monitor that is HDCP 2.2 and HDMI 2.0a for HDR and a UHD player that can read the disk. Whew almost makes this a pointless endeavor. There are plenty of HTPC systems or folks who would like to be able to play this option without having to have a separate player.
no, no, no
It will play 4k FILES!!! IT WILL ABSOLUTELY NOT play a UHD Bluray disc.
